[sane-devel] problems with Fujitsu M3093DG with USB/SCSI

Hi,

I think I fixed the problem.  The SCSI read was returning EOF, and the 
driver wasn't incrementing its buffers properly in that case.  I changed 
it so it doesn't do anything special on EOF, and always increments by 
i_data_read, and it seems to work now.    Here's a patch against the 
latest source:

Maybe the USB interface caused an EOF that wasn't getting sent with 
plain SCSI?
